YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma
Molecular Oncology, EarlyView.The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

Sumoylation of Smc5 Promotes Error-free Bypass at Damaged Replication Forks [PDF]
, 2019 Replication of a damaged DNA template can threaten the integrity of the genome, requiring the use of various mechanisms to tolerate DNA lesions. The Smc5/6 complex, together with the Nse2/Mms21 SUMO ligase, plays essential roles in genome stability ...

PLOS Genetics, 2019 In all kingdoms of life, DNA is used to encode hereditary information. Propagation of the genetic material between generations requires timely and accurate duplication of DNA by semiconservative replication prior to cell division to ensure each daughter cell receives the full complement of chromosomes.

Emerging role of ARHGAP29 in melanoma cell phenotype switching
Molecular Oncology, EarlyView.This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

Genetic Requirements for Intra-Chromosomal Deletions [PDF]
, 2020 Chromosomal deletions are one of the most dangerous types of DNA damage and often arise as a result of inappropriately repaired DNA double strand breaks (DSB).

A role for chromatin remodellers in replication of damaged DNA [PDF]
, 2011 In eukaryotic cells, replication past damaged sites in DNA is regulated by the ubiquitination of proliferating cell nuclear antigen (PCNA). Little is known about how this process is affected by chromatin structure.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids
Molecular Oncology, EarlyView.This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Cryo-EM structure of a licensed DNA replication origin
Nature Communications, 2017 Origins of replication are licensed by loading of MCM onto DNA, and origin firing depends on interaction with Cdc45 and GINS to form two CMG holo-helicases. Here, authors determine the cryo-EM structures of DNA-bound MCM and visualise a phospho-dependent

Evolution of DNA replication origin specification and gene silencing mechanisms
Nature Communications, 2020 Contrary to most eukaryotes that lack sequence-specific origins of replication, S. cerevisiae origins are defined by specific DNA sequence motifs. Here the authors reveal that multiple subunits of ORC, including Orc2 and Orc4, contribute to the sequence ...
